The present invention relates to a developer refilling prevention device capable of preventing forced refilling of an inappropriate developer.

An image forming apparatus to which the electrophotographic method is applied has a developing cartridge inside the apparatus for containing a developer used for developing an electrostatic latent image.

As the consumption of the developer decreases below the lower limit as the printing job continues, the shortage of the developer is displayed outside the apparatus to allow the user to replenish the developer in the developing cartridge.

Although the developer cartridge is properly replaced or replenished with a developer cartridge, there is a concern that a so-called forced refill may be performed in which the developer cartridge is replenished by damaging the developer cartridge for the purpose of replenishing a defective developer that has not been certified. A typical example of this is to punch a developer cartridge, fill it with a developer, and then use the developer cartridge again.

In the past, the necessity of refilling the developer was confirmed by accumulating the number of prints according to the print job, but this method cannot effectively prevent the improper use of such a development cartridge, thereby reducing the reliability of the product. It became.

SUMMARY OF THE INVENTION An object of the present invention is to provide a developer refill preventing device capable of preventing an improper refilling operation of a developing cartridge.

The present invention for achieving the above object is a development cartridge containing a developer; A fine electric circuit part having an electric circuit whose electric resistance value changes according to a damaged state of the developing cartridge; A developing information management unit managing information on forced refilling due to damage of the developing cartridge in accordance with electrical resistance of the electrical circuit; And a control unit which receives information about forced refilling due to damage of the developing cartridge and controls an operation of limiting a print job.

The fine electric circuit unit is embedded in the developing cartridge.

The fine electrical circuit portion is coated with an insulating material.

The display unit may further include a display unit for displaying an error when a forced refill occurs due to damage of the developing cartridge.

The apparatus may further include a power supply unit for supplying driving power to the fine electric circuit unit under the control of the controller.

The phenomenon information management unit may include: a resistance detector configured to detect an electrical resistance of the fine electrical circuit unit, and a comparison unit configured to compare the detected electrical resistance with a preset reference value; And a storage unit for storing information according to the damage of the developing cartridge according to the comparison result of the comparison unit.

Hereinafter, a developer refill prevention apparatus according to an embodiment of the present invention will be described.

The developing cartridge to be applied to the present invention is provided with a supply port for supplying a developer, and is used for a print job by using a developer flowing out through the supply port. If the developer of the developing cartridge is consumed and needs to be replenished, the developer can be replenished through the supply port.

The present invention is to prevent inadequate refilling of the developer cartridge in addition to the supply port provided in the development cartridge, and to install a fine electrical circuit in the development cartridge to recognize the damaged state of the development cartridge and to limit the printing operation accordingly. To be able.

An image forming apparatus to which the electrophotographic method is applied includes a developing unit 10, as shown in FIG. 1, for developing an electrostatic latent image. This developing unit 10 includes a developing cartridge 10a which is shaped to be mounted inside the apparatus, and is configured to receive a developer therein.

As shown in Fig. 2A, the minute electric circuit section 11 is embedded in the developing cartridge so as to detect a state in which the hole is damaged by the outside of the developing cartridge 10a.

As in the outer region A of FIG. 1, the fine electric circuit portion 11 can be selectively disposed at a portion where the development cartridge is easily drilled.

More preferably, the fine electrical circuit part 11 is coated and installed with an insulating material 12 for electrical insulation. As shown in FIG. 2B, the fine electric circuit unit 11 is configured to electrically constitute one closed circuit. When the developing cartridge is damaged and a part of the closed circuit is shorted or disconnected, the electrical resistance is changed accordingly. Is done. On the basis of the change in the electrical resistance, it is possible to recognize whether the development cartridge is damaged, and when an inappropriate refill is detected, the printing operation can be restricted or displayed to the user.

Referring to FIG. 3, the developing unit 10 includes a developing cartridge 10a and a developing information management unit 10b.

The minute electric circuit part 11 embedded in the development cartridge 10a is connected to the power supply 20 to receive the driving power Vp. The power supply unit 20 provides driving power to the fine electric circuit unit 11 under the control of the control unit 30.

The development information management unit 10b is connected to the development cartridge 10a and includes a resistance detector 13, a comparison unit 14, and a storage unit 15.

The resistance detector 13 detects the electrical resistance of the fine electrical circuit unit 11 and provides the detected electrical resistance value to the comparison unit 14.

The comparison unit 14 compares the provided detection resistance value with a preset reference value and provides the storage unit 15 with information about whether the developing cartridge is damaged according to the comparison result.

The storage unit 15 stores information on whether or not the developing cartridge received from the comparison unit 14 is damaged.

The controller 30 controls the printer engine 60 according to a user setting command input through the input unit 50 to perform a print job. The controller 30 may receive information related to the developing unit 10 from the developing information management unit 10b. At this time, the controller 30 receives information on whether the development cartridge 10a is damaged or not from the storage unit 15 according to the electric resistance of the fine electric circuit unit 11. In the event of damage of the developing cartridge 10a, the control unit 30 causes the display unit 40 to display an error due to forced refilling so that the user can take appropriate countermeasures, and the control unit 30 can By controlling the engine 60 to limit the print job, the print operation can be interrupted.

Hereinafter, the operation of the developer refill prevention apparatus according to the present invention will be described.

When power is supplied to the apparatus, when the developing unit is replaced, the control unit 30 provides the driving power Vp to the fine electric circuit unit 11 through the power supply unit 20 (100).

The resistance detection unit 13 detects the electrical resistance of the fine electric circuit unit 11 (102), and the comparison unit 14, which has received the detected electrical resistance value, compares the reference value with respect to whether the development cartridge is damaged or not. To the storage unit 15 (104).

The controller 30 determines whether a forced refill has occurred based on information on whether the developing cartridge is damaged in the storage unit 15 (106), and if the forced refill occurs as a result of the determination, controls the printer engine 60 By limiting the print job 108 and displaying an error due to a forced refill through the display unit 40, the user can take a corresponding action (110). If the forced refill does not occur as a result of the determination, the control unit 30 performs a formal printing job by using the printer engine 60 (112).

As described above, the present invention can effectively prevent improper forced refilling of the developer cartridge to replenish the developer, thereby increasing the reliability of the product.
